I really really wanted one of these retractable brushes. Real techniques brushes make up most of my brush collection because I find them EXcellent quality. When I saw they made retractable, I jumped on it! The quality of this brush is amazing, as is expected. Duo fibers make it really soft and nice. My problem is the bristles are very long and it's a bit more difficult to work with because of that. I prefer a shorter, denser brush. The cap is solid, I've had it in my bag about a week now and it hasn't fallen off. The brush is VERY large, and I have a small face, so it does take up a lot of real estate in my bag and on my face.. I used it to apply my bronzer and it did an OK job, basically I'll settle for this "on the run" brush but prefer to use a different brush IF time allows. Also, the piece that slides up to collect the bristles is stamped "real techniques" all around, and I feel like it makes it look just a little cheap. That's just my opinion, I'd prefer a more sleek look.
